1 Kings 20:22

And the prophet [obviously the same prophet] came to the king of Israel, and said unto him, Go, strengthen thyself [both as to army and to city], and mark, and see what thou doest ["Take every precaution. Don't think that the danger is past"]: for at the return of the year [in the following spring. There was a favourite time for campaigns ( 2 Samuel 11:1 ), viz; when the rainy season was past. Several late wars, notably those of our own armies in Africa and Afghanistan, have been considerably influenced by the seasons. And the wars of ancient times were almost universally summer raids. "Sustained invasions, lasting over the winter, are not found until the time of Shalmaneser" ( 2 Kings 17:5 ; 2 Kings 18:9 10, Rawlinson)] the king of Syria will come [Heb. cometh ] up against thee.
